Professional Air Conditioning Wiring in McLoud, OK

Air conditioning wiring is the backbone of a cooling system that runs efficiently and safely. Your condenser, compressor, and air handler all depend on properly sized circuits that match the equipment nameplate. When the wiring is undersized or installed incorrectly, you face nuisance breaker trips, overheating, and premature equipment failure. At 24/7 Electrical Services and Repairs, we wire each unit to the manufacturer specifications and the National Electrical Code. We calculate the minimum circuit ampacity and the maximum overcurrent protection before we ever pull a single wire. That careful approach protects your investment and keeps your warranty intact. Our licensed electricians also install the outdoor disconnect within sight of the condenser, exactly as code requires. We use weatherproof conduit and the correct whip connection so the outdoor wiring holds up against rain, heat, and time. Low voltage thermostat wiring gets the same attention, including the C wire that modern smart thermostats need. Every connection is torqued to spec, labeled, and tested before we leave. You get honest, upfront pricing and a clean install with no shortcuts. That is the standard our McLoud neighbors have come to expect from us.

I had a very positive experience with 24/7 Electrical Services. Jonathan was professional, knowledgeable, and instrumental in helpings figure out the most cost effective way to get our greenhouse wired from our house. He communicated with us very well and got estimates to us quickly. He made extra efforts to find a solution for us. The electricians were polite, friendly and showed up on time. They got the job done in a timely manner. I would definitely use 24/7 again and would highly recommend them.

24/7 was recommended. I feel I could not have made a better choice for the repairs needed. Brian came out, was super nice, very professional, straight forward, and told me exactly what needed to be done. I accepted the quote, and within minutes, he called me back, set up an appointment. he showed up early, and finished the repairs in less time than quoted. small businesses like 24/7 deserve more from our community. if your thinking about 24/7, just do it, you won't regret it

MaCayla Camren
December 5, 2025

I had a different electrician come replace a breaker panel for me and he was in the attic at one point. He told me there were all kinds of repairs needing done and quoted me a little over $1800 to fix it. I called 24/7 electric out for a second opinion and their guy told me nothing up there was an emergency and the minor things he noticed were easy fixes that I could do myself- like putting connectors on and a box over some spliced and capped wires. He took pictures so he could explain what he saw. I know who to call now for honesty! Thank you 24/7 for saving me a big nonessential expense!!

I did not realize that they were based in McLoud, but they didn't bat an eye about coming to Edmond to give me a free estimate and then followed with the actual install a few days later. The electricians were well groomed and had on identifying shirts & hats. They were professional, efficient & thorough and left the area clean and orderly. I also needed a new switch which he had on the truck and so they installed that too, as well as the two expected light fixtures. I am thrilled with their service and the price was reasonable.

We needed an electrical lamp light post installed but they first had to remove the very old non working gas light, it required digging under a concrete drive and moving river rock out of the way. They also had to change the outside lights. They did all of that in a timely manner. They were very neat putting all the grass back cleaning up the walkways. They were friendly and highly competent. I will use them again.

Scheduled an estimate call to have a Transfer Box installed for a generator when my power goes out. The technician suggested a better way of doing it that would cost me less money (saving money is up my alley). The appointment was scheduled 3 days out, and when the date came, he was early. The job was completed in a timely manner, and the price was very reasonable. It's nice to know that you are not being taken advantage of to make extra money. Outstanding work, and now I'm ready for those power outages, and it didn't hurt my pocket. Thanks Guy's!!!

These are a rare breed in today's day and time. I am a senior citizen age 67 on a fixed income and 100% disabled. I own my home outright and I've put a new roof on it but the storm tore my roof and my pipes completely off by my 50-year-old pecan trees. The water shot through my Hunter ceiling fans and broke them and broke several of my electrical pieces in my home the water damage was very extensive. I was very fortunate as statewide roofing helps me get my home back together again. And now 24/7 came out installed my doorbell fixed my fan to where they had to just take it down and put a new light up so that it would not be dangerous. Not only that they actually put a temporary light up until they could get me one with a cord on it and they didn't have to do that. They also replaced every bulb in my home because I am handicapped and cannot do so. He fixed everything he could possibly fix. The owner took special attention to a little old lady like me and helped me God bless these people they will help you too once a year they help us please take advantage and call them before it would be too late it's every August I believe. what is so awesome about that is they wait until the end of the season to see how much damage has been done to the seniors and they actually help us out with no charge. Gather some things they cannot fix like I need a whole new electrical box and they can't do that but they can help me keep my lights on and keep me safe. And keep me to where I can live in my home and die in it I don't have but maybe 10 years left and I thank them that I don't have to worry those last 10 years. I pray I have longer but we're realistic 67 maybe? Just trying to live in my family home that I've been in since I was a baby and 24/7 electricity has helped me and I'm sure so many other seniors there's no other company like this in Oklahoma City and a lot of people can take heed from these folks. I've asked habitat for humanity I've asked all kinds of help and statewide roofing and 24/7 electric are the only two that would help me as a senior. You guys again I cannot tell you enough how much you have made my life a better place thank you God bless.....

This is my new go-to electrical service company. My dryer wouldn't power on. The dryer repairman said it was a breaker box problem and I would need an electrician to fix it. I called 24/7, and they sent Brian out right away. He confirmed that my breaker box was fine, and even agreed to talk to the dryer repairman. My dryer is now working properly. Since he was at my house any way, I asked Brian to repair a couple of light switches and install a new outlet. He did the job well and quickly, and cleaned up after himself. I was impressed with the responsiveness of the company, and with Brian's efficiency. I'll definitely use 24/7 again.

Called on Sunday and was offered a time for same-day service or another day the upcoming week that fit our schedule. An electrician texted us an hour before he came out and was on-time to appointment. He was kind, easy to understand, and quickly finished our job in just about 30 minutes. He even was able to give us some advice about other electrical questions we had but did not need fixed during this appointment. Will use again if needed!

Margaret Fontaine

The serviceman was extremely pleasant, and very efficient at his job. He took the time to explain to me why my GFI outlet went bad. Then he offered to fix it... as well as put a new separate wall plug in for my refrigerator, so it wouldn't happen again! ( even though it was 8pm at night ) I was very pleased with the service, so I've put their number in my phone, for the next time I need an electrician. Margaret

Air Conditioning Wiring in McLoud, OK

Inside the home, the air handler or furnace blower also needs its own correctly sized and protected circuit. Many modern systems pair a high voltage feed for the blower motor with a separate low voltage control circuit. That control wiring runs at twenty four volts and carries the signals between your thermostat and the equipment. Today’s thermostats, especially smart and Wi Fi models, require a common wire, often called the C wire, to stay powered. Older homes throughout our service area frequently lack that conductor, so a thermostat upgrade sometimes turns into a wiring project. We run brand new low voltage cable whenever it is needed and terminate it cleanly at both ends. Color coded conductors get matched to the correct terminals so the system communicates without confusion or crossed signals. We then test the heating, cooling, and fan calls to confirm every function responds. A miswired thermostat can short cycle the compressor repeatedly and shorten the operating life of an expensive component. Getting the control side right is every bit as important as getting the high voltage power side right.

Load calculations tie the entire project together and keep your electrical panel well within its safe limits. Adding a new air conditioning circuit increases the demand on your service, and not every panel can absorb that addition. We evaluate your existing service size, the breaker space available, and the total connected load before adding the new circuit. If your panel already runs near its limit, we will tell you honestly rather than overload it and create a hazard. A crowded or maxed out panel is a genuine fire risk that no amount of added cooling comfort is worth. Tandem breakers, double tapped lugs, and backfed circuits all show up in older homes, and we correct them as we work. We size the feeder, the breaker, and the conductors together as one matched set, not as separate afterthoughts. Aluminum and copper require different handling, so we use proper terminations and anti oxidant compound wherever code calls for it. Each new circuit gets clearly labeled at the panel so future service work stays straightforward and safe. A clean panel is a safe panel, and we always leave yours in better shape than we found it.

Oklahoma weather places unusual demands on cooling equipment and on the wiring that feeds power to it. Summer temperatures push air conditioners to run for many hours at a stretch, and that sustained load reveals weak connections fast. Heat causes metal to expand and contract, which can gradually loosen terminals that were never torqued to the correct value. We torque every lug and terminal to the manufacturer specification using a calibrated tool, never by feel or guesswork. Storms and lightning are another hard reality here, and a surge can travel right into your condenser through the wiring. That is why we frequently recommend pairing a new cooling circuit with a layer of whole house surge protection. Wind driven rain tests every outdoor seal, so we choose enclosures and fittings built to keep water out. Years of direct sun exposure break down cheap insulation, so we select conductors rated for the real environment. Proper support and strain relief keep cables from sagging or chafing against rough surfaces over the long term. We build your system to handle the demanding climate it actually has to live in, year after year.

Troubleshooting an existing air conditioning circuit is a service we provide nearly as often as brand new installations. When a unit refuses to start, the cause can hide anywhere from the breaker to the disconnect to the contactor. We work methodically, checking voltage at each point rather than throwing replacement parts at the problem and hoping. A breaker that trips the moment the compressor kicks on usually points to a short, a ground fault, or a failing component. A unit that hums but will not turn over often signals a capacitor problem rather than a wiring fault by itself. We isolate the electrical problems from the mechanical ones so you are never paying to chase the wrong repair. Burnt wire, melted insulation, and pitted contacts each tell a clear story, and our electricians know how to read it. Once we locate the root cause, we repair it properly and verify the system runs within specification. We document what we found and what we corrected so you have an honest written record of the visit. Careful diagnosis saves you real money and prevents the same failure from coming back a month later.

Choosing the right electrician for this work protects your home, your family, and your cooling equipment at once. 24/7 Electrical Services and Repairs holds Oklahoma license number 084623, and a licensed professional pulls the permits and works to code. Permitting and inspection are not pointless red tape; they are a second set of eyes confirming the work is safe. We are locally owned and family operated, so our reputation rides on every job we complete in this community. Our pricing stays upfront and honest, with free local estimates and absolutely no surprise charges waiting at the end. We back our work with a one year labor warranty and a three year panel warranty. Emergency service is available around the clock, because a cooling failure in July cannot wait until Monday. We show up on time, treat your home with genuine respect, and clean up thoroughly before we leave the property. The real difference is always in the small details, and those details are where our team shines.

Why Electrical Code Matters for Air Conditioning Wiring

Electrical code exists to keep people safe, and air conditioning wiring falls under some of the most specific rules in the book. Article 440 of the National Electrical Code governs how air conditioning and refrigeration equipment must be wired. It sets the requirements for conductor sizing based on the equipment nameplate rather than a simple guess. It mandates a disconnecting means within sight of the unit so service can be performed safely. Code also dictates the overcurrent protection, which must protect the conductors without nuisance tripping the compressor. Grounding and bonding rules under the code ensure that a fault has a safe path back to the source. Outdoor wiring methods must meet weatherproofing standards that handle Oklahoma’s rain, heat, and humidity. When wiring ignores these rules, the danger ranges from breaker damage to electrical fire. Insurance claims can be denied when an installation fails to meet code, leaving the homeowner exposed. Equipment manufacturers also void warranties on systems that were not wired to specification. Local inspectors verify the work because their oversight catches mistakes before they become hazards. Following code is not optional for us; it is the foundation of every air conditioning circuit we install.

Most Common Air Conditioning Wiring Questions

AC wiring raises plenty of questions, from circuit sizing to disconnect placement to thermostat compatibility. We have answered the ones our McLoud customers ask most so you know what to expect before we arrive.

The correct breaker and wire size for an air conditioner come straight from the equipment nameplate, not from a generic rule of thumb. Manufacturers print two key numbers on that label, the minimum circuit ampacity and the maximum overcurrent protection. The minimum circuit ampacity tells us the smallest conductor that can safely carry the load. The maximum overcurrent protection tells us the largest breaker allowed on that circuit. We size the wire to meet or exceed the minimum ampacity and select a breaker that does not exceed the maximum protection value. A typical residential condenser often lands on a 30 amp double pole breaker with appropriately rated conductors, though yours may differ. Larger systems and heat pumps frequently call for higher amperage and heavier wire. The only way to know for certain is to read your specific equipment label.

Using the wrong size creates real problems that show up over time. A breaker rated too high will not trip when the conductor is overloaded, which allows the wire to overheat. A breaker rated too low will trip every time the compressor starts, leaving you without cooling. Conductors that are too small for the load run hot and degrade their insulation, raising the risk of a short or fire. Copper and aluminum also carry current differently, so the same amperage may require a different gauge depending on the metal. Wire length matters too, because long runs introduce voltage drop that can call for an upsized conductor. We account for all of these variables on every job. The math is precise, and we do it before we cut anything.

This is exactly why hiring a licensed electrician pays off on an air conditioning circuit. We have the tools to verify voltage, the training to interpret the nameplate, and the experience to spot complications. Guesswork on a 240 volt circuit is dangerous and expensive. A proper install protects your compressor, your home, and your warranty all at once. If you are replacing an existing unit, the new equipment may have different requirements than the old one. We never assume the old circuit is adequate just because it powered the previous system. We confirm the numbers, upgrade what needs upgrading, and document the result. That is how you get a circuit that performs and lasts.

The disconnect box near your outdoor unit is a safety requirement built directly into the electrical code. Its purpose is simple, to give a technician a way to cut power right at the equipment before servicing it. Imagine a worker on the roof or beside the condenser with no way to kill the power except the breaker inside the house. That distance creates a serious risk, because someone could restore power while the technician is exposed. The code solves this by requiring a disconnecting means within sight of the unit. Within sight has a specific meaning, generally visible and not more than fifty feet away. This local control lets a service tech lock out the power and work with confidence. It is one of the most important safety devices on the entire system.

The disconnect also protects the equipment and the wiring in everyday operation. A weatherproof enclosure shields the connection point from rain, dust, and the relentless Oklahoma sun. Inside that box, you typically find either a pull out block or a switch that breaks both hot legs of the 240 volt circuit. Breaking both legs is critical, because cutting only one leg can leave the unit partially energized. We install disconnects rated for outdoor use with proper gaskets and entry seals. The whip that runs from the disconnect to the condenser flexes with vibration and keeps the wiring protected. Corroded or improperly sealed disconnects are a frequent source of intermittent failures. We make sure yours is mounted level, sealed tight, and wired correctly.

Skipping or relocating a disconnect to save a few dollars is never worth the risk. An installation without a proper disconnect will fail inspection, and for good reason. It also puts every future service call in jeopardy, since the next technician has no safe way to isolate the unit. If your current setup lacks a disconnect or uses a damaged one, we can correct it quickly. We position it where code requires and where access is convenient for service. The right disconnect is a small component with an outsized role in safety. We treat it with the importance it deserves. Your equipment and the people who service it depend on it.

Adding a new air conditioning circuit depends entirely on what your existing panel can handle. The first thing we check is the available space, because a new 240 volt circuit needs two open breaker slots. Many older panels are already full, which forces a decision between tandem breakers, a subpanel, or a service upgrade. Beyond physical space, the real question is capacity, meaning how much total load your service can safely carry. A 100 amp service that is already running a full household may not have room for a power hungry condenser. We perform a load calculation that adds up your existing demand and compares it to your service rating. If the numbers leave enough headroom, the new circuit can land on your current panel. If they do not, we will tell you honestly rather than overload the system.

Overloading a panel is a genuine hazard that we take seriously on every job. When the connected load exceeds what the service was designed to carry, the main breaker trips or worse. Bus bars overheat, terminals loosen, and the risk of an electrical fire climbs. We also look for existing problems while we are in the panel, such as double tapped breakers or aluminum branch wiring. Those issues do not disappear when you add a circuit; they often get worse under additional load. A crowded panel with no labeling makes future service slow and risky. We straighten out what we find and document the changes. The goal is a panel that is safe today and easy to work on tomorrow.

If your panel cannot accommodate the new circuit, we have solid options that fit your needs and budget. A service upgrade to 200 amps gives most homes plenty of room for cooling, EV charging, and future additions. A subpanel can also create dedicated space closer to the equipment when that makes sense. We walk you through the choices with upfront pricing and no pressure. As panel upgrade specialists, this is work we do every week across McLoud and the surrounding area. We pull the permit, coordinate any utility steps, and handle the inspection. You end up with capacity that serves you for years rather than a stopgap that fails. Doing it right the first time always costs less than fixing a shortcut later.

The C wire, short for common wire, is the conductor that delivers continuous low voltage power to a thermostat. Older thermostats were mechanical and drew almost no power, so they ran fine without one. Modern thermostats are different, packed with displays, Wi Fi radios, and processors that need steady power to function. Without a dedicated common wire, these smart devices try to steal power from other terminals, which causes glitches. You might see a thermostat that randomly reboots, drops its connection, or short cycles the system. The C wire solves all of that by giving the thermostat a stable 24 volt supply. It completes the low voltage circuit back to the control board in your furnace or air handler. That steady power is what keeps a smart thermostat reliable.

Many homes in our area were wired before smart thermostats existed, so the C wire simply is not there. When a homeowner upgrades to a Wi Fi thermostat, this missing conductor becomes an unexpected obstacle. We run a new low voltage cable from the equipment to the thermostat location to add the wire. In some cases an add a wire adapter can work, but a proper dedicated conductor is the cleaner solution. We match the new wiring to the existing color code so the connections stay clear and correct. At the control board, we land the common wire on the right terminal and verify the voltage. At the thermostat, we confirm the device powers up and holds its connection. Every heating and cooling function gets tested before we consider the job complete.

Getting the control wiring right matters as much as the high voltage side of the system. A thermostat that cannot hold power can short cycle your compressor, and short cycling shortens its life dramatically. Miswired terminals can cross signals and cause the system to heat when it should cool. We take the time to trace each conductor and confirm it lands where it belongs. If your old thermostat wiring is brittle or damaged, we replace it rather than nurse it along. Clean, correct low voltage wiring makes your smart thermostat perform the way the manufacturer intended. It also makes future upgrades painless. When you are ready for a new thermostat, the wiring should never be the thing holding you back.

Several warning signs point to trouble in your air conditioning wiring, and catching them early saves money. A breaker that trips when the unit starts is one of the clearest signals something is wrong. Lights that dim noticeably each time the compressor kicks on can indicate a voltage drop or a strained circuit. A burning smell near the outdoor unit or the panel is a serious red flag that demands immediate attention. Warm or discolored cover plates, outlets, or breakers suggest heat building up where it should not. If your system runs but struggles to cool, a wiring or connection issue may be limiting its power. Buzzing sounds from the disconnect or contactor often mean loose connections or arcing. Any of these symptoms is worth a professional inspection before it grows into a failure.

Some wiring problems hide where you cannot easily see them, which is why diagnosis matters. Loose terminals are a common culprit, since they create resistance, heat, and eventual damage. Corroded connections at an outdoor disconnect can interrupt power intermittently and frustrate any homeowner. Rodents sometimes chew through low voltage thermostat wiring, causing strange and inconsistent behavior. Insulation that has degraded from heat or age can short against metal surfaces. A failing capacitor or contactor can mimic a wiring fault, so we test to tell them apart. We use meters to check voltage and continuity at each point in the circuit. That methodical approach finds the true cause instead of masking the symptom. Guessing wastes money and rarely fixes the real issue.

When you notice any of these signs, the safest move is to call a licensed electrician promptly. Continuing to run a system with a wiring fault risks damage to an expensive compressor. It also raises the chance of an electrical fire, which is never worth the gamble. We respond quickly across McLoud and the surrounding communities, with emergency service available around the clock. Our team isolates the problem, explains what we found, and gives you upfront pricing before any repair. We fix the root cause and verify the system runs within spec before we leave. You receive a clear record of the work and the peace of mind that follows. Catching a small issue early almost always beats paying for a major failure later.

In most cases, yes, air conditioning wiring requires a permit, and that requirement protects you as the homeowner. A permit triggers an inspection, which is an independent check that the work meets the electrical code. New circuits, panel changes, and equipment installations typically fall under permitting rules. Permits exist to confirm that conductors are sized correctly, disconnects are placed properly, and grounding is sound. Skipping the permit might seem like a way to save time, but it creates real risk down the road. Unpermitted work can surface during a home sale and force costly corrections at the worst moment. It can also give an insurance company grounds to deny a claim after a fire or failure. A permit is cheap insurance against all of those headaches.

We handle the permitting process so you never have to navigate it alone. As a licensed Oklahoma contractor, we know which jobs require permits and how to file them correctly. We coordinate the inspection and meet the inspector on site when needed. That oversight benefits you, because a second qualified set of eyes confirms the installation is safe. Inspectors look for the same details we already build into every job, from torque values to disconnect placement. Passing inspection is rarely a worry for our work, because we wire to code from the start. The permit becomes a paper trail proving the job was done correctly. That documentation adds value and protects your investment.

Some homeowners worry that permits add cost and delay, but the reality is the opposite over time. The small permit fee is minor compared to the expense of correcting unpermitted work later. An inspection can catch a hidden mistake before it becomes a dangerous or expensive problem. Permitted work also keeps your equipment warranty and your homeowner insurance intact. When you hire us, the permitting is simply part of the service, handled professionally and without hassle. We believe in doing the job the right way, all the way through. Cutting corners on permits is not how a reputable electrician operates. You deserve work that stands up to inspection and stands the test of time.

A breaker that trips repeatedly when your air conditioner runs is the system telling you something is wrong. The breaker is a safety device, and it cuts power the moment it senses more current than the circuit can safely handle. Sometimes the cause is a simple overload, where the circuit carries more load than it was sized for. Other times the trip points to a short circuit, a ground fault, or a failing component inside the unit. A dirty condenser coil or a low refrigerant charge can force the compressor to work harder and draw extra current. A failing capacitor often makes the compressor struggle to start, which spikes the amperage and trips the breaker. Loose connections at the panel, the disconnect, or the contactor create resistance that generates heat and nuisance trips. The pattern of when it trips usually gives us the first clue about where the fault lives.

The age and condition of the breaker itself can also play a role in repeated tripping. Breakers wear out over time, and a weak one may trip below its rated amperage even on a healthy circuit. Heat is the enemy of any electrical connection, and a breaker that has tripped many times can lose its calibration. We never recommend simply resetting a breaker again and again, because that ignores the warning it is sending. A breaker that trips the instant the compressor engages usually signals an electrical short rather than a slow overload. A breaker that trips after the unit runs for a while more often points to heat buildup or an overload condition. Wiring that has been damaged by rodents, moisture, or age can short intermittently and produce confusing symptoms. We test under real operating conditions so the fault reveals itself instead of hiding.

Chasing a tripping breaker without the right tools wastes money and can leave the real hazard in place. Our electricians measure the actual current draw and compare it to the equipment nameplate and the breaker rating. We check voltage at every point in the circuit, inspect the contactor and capacitor, and look for heat damage. If the breaker is undersized for the equipment, we correct the circuit rather than just swap in a larger breaker. Installing a bigger breaker to stop the tripping is dangerous when the wire cannot handle the added current. We find the true cause, fix it, and confirm the system runs within its rated draw before we leave. You receive a clear explanation of what failed and what we did to repair it. A breaker that keeps tripping is never something to ignore, and we are ready to track it down.

Wiring an air conditioner is not a project we recommend tackling on your own, and the reasons go beyond convenience. Air conditioning circuits run on 240 volts, which carries enough energy to seriously injure or kill someone who makes a mistake. The work also falls under Article 440 of the National Electrical Code, with specific rules for sizing, disconnects, and grounding. Getting the conductor and breaker sizing wrong can create a fire hazard that may not show itself until months later. Many areas require a permit and an inspection for this work, and unpermitted wiring can cause problems during a home sale. Equipment manufacturers frequently void the warranty when the unit is not installed by a licensed professional. A small error in the low voltage thermostat wiring can short cycle and destroy an expensive compressor. The stakes are simply too high for trial and error on a circuit this powerful.

There is also a large gap between knowing how to connect two wires and knowing how to wire a system correctly. A licensed electrician reads the equipment nameplate, performs a load calculation, and verifies the panel can handle the new circuit. We know how to install a code compliant disconnect, seal the outdoor connections, and bond the ground properly. We torque every terminal to specification, because a loose lug generates heat that a homeowner would never notice. We carry meters that measure voltage, continuity, and current draw to confirm the install is safe before energizing. We also spot existing panel problems, like double tapped breakers or aluminum wiring, that a typical homeowner would miss. Insurance and liability are real concerns too, since a fire traced to unpermitted work can lead to a denied claim. These are the protections that come with hiring a trained professional rather than guessing.

If you enjoy hands on projects, there are plenty of safe ways to be involved without touching the wiring yourself. You can keep the area around the condenser clear, change your filters, and watch for the warning signs we describe. When something seems wrong, calling a licensed electrician early almost always costs less than repairing a bigger failure. We offer free local estimates, so you can understand the scope and price before any work begins. Our pricing is upfront and honest, with no surprise charges added at the end of the job. We pull the permit, handle the inspection, and back the work with our warranty for your protection. You get a safe, code compliant installation without the risk that comes from doing it yourself. When you are ready, our McLoud electricians are a quick phone call away.
